It's a question about the license for envato elements

Greetings,

I am a freelance videographer from S. Korea. Upon inspecting Envato Element’s license, there is a clause that states:

You Cannot Use Items in On-Demand, Made to Order or Build Yourself Applications
Items on Envato Elements cannot be offered in on-demand services (eg: a site where a customer customizes a design of a t-shirt for order). Whether the end result is a digital or physical product, this use is prohibited.

Within the clause, I am unsure about the exact usage of the word “on-demand.” Is it used to denote contracted outside work, or commercial products such as purchasable IPTV material?

Should it mean outside contracts, would it be possible to use said media for Youtube and/or other platforms?

Thank you for your time and awaiting your reply,
Regards,
